Abstract: Selon l'invention, on détecte des signaux acoustiques à distance au moyen d'un faisceau laser cohérent à impulsions (20), projeté à partir d'un télescope (19) en direction d'une région à distance (21) laquelle contient des signaux acoustiques provenant d'une source proche et non illustrée. La lumière du faisceau (20) est diffusée dans la région (21) et un signal résultant (23) est recueilli par un télescope (24). Le signal (23) et un signal de référence (27) sont appliqués à un interféromètre (26) et le motif d'interférence résultant (28) est appliqué à un photorécepteur (29). Un courant alternatif (30) est produit dans le photorécepteur (29), correspondant à la lumière diffusée à partir du faisceau par suite du déplacement périodique des signaux acoustiques à travers la région (21). On peut utiliser ce détecteur (10) pour déterminer la courbe d'un front d'onde de signaux acoustiques et pour détecter l'emplacement d'une source produisant ces signaux acoustiques.

Abstract: A three-stage lean burn combustion chamber (28) comprises a primary combustion zone (36), a secondary combustion zone (40) and a tertiary combustion zone (44). Each of the combustion zones (36,40,44) is supplied with premixed fuel and air by respective fuel and air mixing ducts (54,70,92). The fuel and air mixing ducts (54, 70, 92) have a plurality of air injections apertures (62,64,76,98) spaced apart in the direction of flow through the fuel and air mixing ducts (54,70,92). The apertures (62,64,76,98) reduce the magnitude of the fluctuations in the fuel to air ratio of the fuel and air mixture supplied into the at least one combustion zone (36,40,44). This reduces the generation of harmful vibrations in the combustion chamber (28).

Abstract: Dispensing nozzle has a dosing cavity in selective communication with the inside of the product container via inlets. The cavity is formed between two pistons able to slide inside a fixed chamber to deliver a controlled volume of the product to an outlet fitted with a teat-shaped reversible membrane with a slit. Dispensing nozzle (1) has a dosing cavity (20) in selective communication with the inside of the product container (6) via inlets (28, 29). The cavity is formed between two pistons (21, 25) able to slide inside a fixed chamber (9) to deliver a controlled volume of the product to an outlet (8) fitted with a teat-shaped reversible membrane (31) with a slit (32). As it approaches the outlet the first piston is stopped by a shoulder (12) on the inner wall of the fixed chamber, while the second piston continues its travel to expel the product, the force being produced by pressure on the container walls.

Abstract: A method of attenuating noise in three dimensional seismic data using a projection algorithm is disclosed. A frequency-space-space ("f-xy") projection algorithm is used which is a generalization of the f-x projection algorithm. The predictability of the seismic signals in the f-xy domain constitutes the basis of the algorithm. Specifically it is demonstrated that if the seismic events are planar in the t-xy domain, then in the f-xy domain they consist of predictable signals in the xy-plane for each frequency f. A crucial step of the 2-D spectral factorization is achieved through the helical coordinate transformation. In addition to the disclosed general algorithm for arbitrary coherent noise, a specialized algorithm for random noise is disclosed. It has been found that the disclosed projection algorithm is effective even in extreme cases of poor signal to noise ratio. The algorithm is also signal preserving when the predictability assumptions hold.

Abstract: A mobile station (110) selects an initial data rate for communication between base station (107) and mobile station (110). Mobile station (110) communicates the selected initial data rate to base station (107) through uplink (112). Base station (107) determines a difference level of interference condition experienced by mobile station (107) between a time when the initial data rate was selected by mobile station (110) and a time when base station (107) prepares to communicate to mobile station (110). Base station (107) selects a final data rate for transmission from base station (107) to mobile station (110) based on the determined difference level of interference condition. As such, the initial data rate may be modified to the final data rate while maximizing the down link capacity.

Abstract: Techniques for providing secure communications between two or more end units of a call processing system via a call complex or other communication system switch. The end units each generate a set of session key lists including a stack-based session key list for each of the terminals coupled thereto. The multiple sets of session key lists are communicated from the end units to the call complex in a secure manner as part of corresponding authentication protocols carried out between the end units and the call complex. In establishing secure communications between an originating end unit and one or more additional end units, the call complex selects, as an end unit to end unit session key, a session key from a session key list in a given one of the sets of session key lists associated with the originating end unit. The selected end unit to end unit session key is used to provide secure communications between the originating end unit and at least one other end unit via the call complex. The same end unit to end unit session key is preferably used for any additional end units subsequently conferenced into the secure communication channel between the originating end unit and a specified destination end unit. Upon termination of the secure communication channel, one or more new session keys can be generated for the affected terminals so as to maintain a desired minimum stack size for the session key lists.

Abstract: Naturally occurring polarization-induced electric fields in a semiconductor light emitter with crystal layers (2-7) grown along a polar direction are reduced, canceled or reversed to improve the emitter's operating efficiency and carrier confinement. This is accomplished by reducing differences in the material compositions of adjacent crystal layers (2-7), grading one or more layers to generate space charges and quasi-fields that oppose polarization-induced charges, incorporating various impurities into the semiconductor that ionize into a charge state opposite to the polarization induced charges, inverting the sequence of charged atomic layers, inverting the growth sequence of n- and p-type layers in the device, employing a multilayer emission system instead of a uniform active region and/or changing the in-plane lattice constant of the material.

Abstract: The present invention generally relates to systems and methods for providing information about chromophores in physiological media. More particularly, the invention relates to non-invasive systems and methods for determining absolute values of oxygenated and/or deoxygenated hemoglobins and their ratios in a physiological medium. The system generally includes a portable probe having a source module (122) for irradiating into the medium electromagnetic radiation, a detector module (124) detecting radiation from a target area in the medium, and a processing module (140) determining the absolute values of the chromophore concentrations and the ratios thereof based on input and output parameters of the source and detector modules. In one aspect, the invention provides a solution for unknown parameters of the chromophores in a medium using a novel processing algorithm. In another aspect, the invention concerns a portable unit for performing the requisite measurements, which unit includes a movable member having one or more radiation sources and one or more radiation detectors, and an actuator designed to cause the member to move along predetermined curvilinear paths. Properties of the chromophores are measured for individual voxels defined along each motion path, and/or cross-voxels defined at the intersection of voxels along different motion paths.  These measured values are then used in a preferred embodiment to generate two-or three-dimensional images of the distribution of chromophores or their properties. In other aspects, the invention includes various patterns for the optimal distribution of sources and detectors for the optical probe, and self-calibrating operation of the probe substantially in real-time.
